Lie on your back on an incline bench set between 15 and 30 degrees, and hold a pair of dumbbells above your shoulders with your arms straight. Lower the dumbbells to the sides of your chest. Pause, and then push them back up. Do 10 reps and rest for 20 seconds. Decrease the weight of the dumbbells by 20 to 30 percent and perform 10 more reps.

Assume a pushup position with your hands on a bench. (The higher the bench, the easier the exercise.) Your body should form a straight line from ankles to head. Bend your elbows and lower your body until your chest nearly touches the bench. Then push up with enough force so your hands leave the bench. Land with your hands on the bench and repeat. Do 5 to 10 reps.

Hang at arm's length from a chinup bar using an overhand grip that's slightly beyond shoulder width. Squeeze your shoulder blades together and pull your chest to the bar. Pause, and then return to the starting position. Do 5 to 10 reps.

Secure a bar in a power rack at about waist height. Drape two towels over the middle of the bar so they're slightly beyond shoulder width. Grab the ends and hang from them with your knees bent, your feet flat on the floor, and your body straight from knees to head. Pull your chest toward the bar. Pause, and then slowly return to the starting position. Do 10 reps.

Hold a dumbbell in your right hand, place your left hand on a bench in front of you, and assume a staggered stance, left foot forward. Hold your elbow in as you row the wight to the side of your torso. Do 10 reps, switch arms and leg positions, and repeat the movement.

Grab a pair of dumbbells, bend your knees and lean forward so your torso is nearly parallel to the floor. Tuck your upper arms next to your sides, bend your elbows, and hold your forearms about parallel to the floor, palms facing up. Simultaneously extend your arms straight back and rotate the weight so your palms end up facing each other. Return to the starting position. Do 15 reps.

Standing with your feet shoulder-width apart, hold a pair of dumbbells at arm's length by your sides, palms facing each other. Without moving your upper arms, curl the weights to your shoulders, and then press them overhead until your arms are straight. Reverse the move to return to the starting position. Do 10 reps.

Muscular Strength Versus Muscular Endurance

Muscular endurance is trained specifically and in more of an aerobic and oxygenated pathway, whereas muscular strength is trained in an anaerobic ATP-CP and Glycolytic pathway.

There does seem to be a relationship between muscular strength and muscular endurance. However if a person only trains to improve strength then that person is not improving his muscular endurance that much.

The definition of muscular strength is: the ability of your body's muscle to generate force in a short period of time. This type of activity relies on anaerobic energy--allowing you the short burst of energy you need to lift a heavy weight. When you increase your strength, you're often also increasing the size of your muscles as well as strengthening your connective tissues.

On the other hand the definition of muscular endurance is: the ability to sustain muscle contraction over a period of time without undue fatigue.

By looking at these definitions we can see that muscular strength involves using heavier weights for a shorter period of time, and muscular endurance involves using a moderate weight for a longer period of time. The pathways utilized are different for each. For muscular strength the pathway utilized would be more ATP-CP and some glycolysis, and muscular endurance would utilize more of glycolysis and oxygen pathways.

The physiology of a muscle is that each muscle contains muscle fibers. Each fiber is innervated by a single axon; a motor neuron may have a hundred or more axons. A single motor neuron, with all the fibers it controls, is a motor unit. As the brain's signal for contraction increases, it both recruits more motor units and increases the "firing frequency" of those units already recruited. Even during a "maximal voluntary contraction", it is unlikely that all the motor units are activated. All joints, however, are set up as lever systems: the fulcrum where two bones meet, one force produced by the muscle, and the other by a load. Strength is not just muscle force, but muscle force as modified by the mechanical advantage of the joint. To complicate matters further, this mechanical advantage usually varies with joint rotation, as does the muscle force. The net result is strength that varies with joint angle and may be somewhat decoupled from muscle force. Joint strength can be increased with exercise.
